Question

I have the following array, named $usergrouppermissions:

Array (     [0] => Array         (             [UserGroupPermission] => Array                 (                     [group_id] => 1                     [permission_id] => 4                 )          )      [1] => Array         (             [UserGroupPermission] => Array                 (                     [group_id] => 1                     [permission_id] => 5                 )          )      [2] => Array         (             [UserGroupPermission] => Array                 (                     [group_id] => 1                     [permission_id] => 6                 )          )      [3] => Array   [...] 

In a loop, i build another array like this, named $searchme:

Array (     [UserGroupPermission] => Array         (             [permission_id] => 1             [group_id] => 1         )  ) 

Now, i want to check, if given array above exists in the numeric-indexed array at the top. I currently do this:

$result = Set::contains($usergrouppermissions, $searchme); 

The result is always false. Do i get something wrong here? What is the problem?

Answer 1

Since PH 4.2 in_array can also use arrays as needle. So, the solution is this:

in_array($searchme, $usergrouppermissions)
